| چکیده | ||
| در قسمت اول تحقیق مبدل گاز طبیعی غیرکاتالیستی به روش عددی تحلیل می‌گردد. معادله‌های حاکم شامل معادله بقای جرم، اجزا با مدل احتراقی، اتلاف‌های گردابی با استفاده از مکانیزم GRI - 1.2، اندازه حرکت و بقای انرژی با مدل آشفتگی رینولدز است. نتایج قسمت اول نشان می‌دهد که افزایش فشار، تبدیل متان به هیدروژن را افزایش می‌دهد اما از فشار 3 مگا پاسکال به بالا تولید هیدروژن تقریباً ثابت می‌ماند. همچنین اگر نسبت اکسیژن به گاز طبیعی تا 66/0 افزایش یابد، دما افزایش یافته و غلظت متان در گاز خروجی کاهش و از طرفی هیدروژن تولیدی افزایش می‌یابد. بعلاوه با افزایش نسبت بخارآب به گاز طبیعی، دما در مبدل کاهش یافته و نسبت هیدروژن به مونوکسید کربن در خروجی افزایش می‌یابد. سپس برای رفع چالش نقطه داغ در این مبدل‌ها، رفورمینگ بخار متان بررسی شد. از معادله‌های بقای جرم، برینکمن، انتقال اجزا و انرژی برای مبدل کاتالیستی چند لوله‌ای استفاده شد. اثر دمای ورودی لوله‌های گرم‌کننده در مبدل کاتالیستی، نسبت متان به بخارآب و همچنین پیکربندی لوله‌ها مورد بررسی قرار گرفت. نتایج نشان می‌دهد که با افزایش دمای ورودی لوله‌های گرم‌کننده، نسبت متان به بخارآب به حدود 0/25 می‌رسد و رفورمینگ افزایش می‌یابد. | ||

| چکیده [English] | ||
| In the first part of the research, non-catalytic natural gas reformer is investigated numerically. The governing equations include the mass equation, the species equation with eddy dissipation concept modeling using GRI-1.2 mechanism, the momentum and energy equation with Reynolds-averaged Navier–Stokes turbulence model. The results show that increasing the pressure promotes conversion of CH4 into hydrogen, but from pressure 3 MPa and above, hydrogen production remains almost constant. Also, if the ratio of oxygen to natural gas increases to 0.66, the temperature increases and the concentration of CH4 in the exhaust gas decreases In addition, as the ratio of water vapor to natural gas increases, the temperature in the reformer decreases and the H2/CO (synthetic gas) ratio in the output increases. In the next section, methane steam reforming is examined to overcome the hot spot problem in these reformers. The mass, Brinkman, component and energy transport equation are used for the multi-tube catalytic reformer. The effects of inlet temperature of heating tubes, CH4/H2O ratio and configuration of heating tubes have been investigated. The results show that increasing the inlet temperature of the heating tubes, the CH4/H2O ratio up to 0.25 and the number of heating tubes, increase methane reforming. | ||
